Specification of Letters Patent.

Patented Dec. 81, 1907.

Application filed July 19,1906. Serial No. 326,953,

To all whom it may concern:

Be it known that I, FRANK L. CAsPER, a citizen of the United States,residing at l/Veiner, in the county of Poinsett, State of Arkansas, haveinvented certain new and useful Improvements in Blacksmith-Tongs; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to tongs and more particularly to those for usein farriery, and has for its object to provide a pair of tongs soconstructed that its gripping lips will lie in parallel relation topresent the maximum of gripping surface to the object to be held.

Another objectis to provide a pair of tongs with which one lip will beremovable to permit of substitution of lips of difierent forms therefor.

Other objects and advantages will be apparent from the followingdescription, and it is to be understood that I do not desire to belimited to the exact details of construction shown and described, forobvious modifications will occur to a person skilled in the art.

In the drawings forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is a side elevation of the tongs. Fig. 2 is a front view,showing the ends of the lips. Fig. 3 is a detail sectional view throughthe finger and movable lip. Fig. 4 is an elevation through the fingerand a modified form of the movable lip, having a longitudinal roove inits gripping surface. Fig. 5 is an elevation of a different form oftongs embodying the present invention. Fig. 6 is a longitudinal section.

Referring now to the drawings, the present invention comprises twohandles 5 and 6 rounded at their forward .ends, and these roundedportions are disposed against each other and are pivoted together, asshown. The handle 6 has a lip 7 extending forwardly from its roundedportion and laterally therebeyond, this jaw being cut away and recessedat its rearward portion, as shown at 8, to receive the rounded portionof the handle 5.

The rounded portion of the handle 5 has a finger 9 extending outwardlyand forwardly therefrom at its opposite side from the lip 7, the freeend of this finger being turned toward the lip, and this finger isoffset laterally from the plane of the handle 5 adjacent to its innerend to form a shoulder 10 extending over the rounded portion of thehandle 6, and forming also a shoulder 11 at the base of the finger. Alip 12 has parallel wings 12 which lie in spaced relation and in the lipbe tween these wings a concavity 13 is formed, the curvature extendinglongitudinally of the lip. The finger 9 lies between the wings 12 withits forward rounded end in the 7, concavity 13, a pivot pin 14 beingpassed through the wings and the lip at the forward portions thereof,the rearward portion of the lip 12 is thus movable toward and away fromthe lip 7, and laterally extending projections 15 are carried by theinner portions of the wings 12, one extending over the forward roundedportion of the handle 5, and the other over the corresponding portion ofthe handle 6, for engagement of these rounded portions to limit thepivotal movement of the lip 12 toward the lip 7.

It will be readily understood that when a body is grasped between thelips, the lip 12 will move upon its pivot to conform to the shape of thebody and will present the greatest possible gripping surface thereto,and by reason of the fact that the forward end of the finger 9 extendsinto the concavity 13 and rests against the bottom thereof, the stressincident to operation of the tongs is removed from the pin 14. Therearward portion of the lip 12 between the wings 12 is rounded, to enterthe concavity caused by the curvature of the finger 9, to permit ofmaximum movement of the lip 12 away from the lip 7.

In Fig. 4 there is shown a structure in which the lip 12 is providedwith a longitudinal groove 17 in its inner surface, and in Fig. 5 theinvention is shown embodied in a pair of tongs having rounded lips 18.

WVhat is claimed is:

A pair of tongs comprising two handles provided adjacent their upperends with enlarged rounded portions, a pivot pin projected centrallythrough said rounded portions, one of said handles having at its upperend a straight inclined inwardly pointing lip, the other handle having acurved inwardly pointing finger, a lip pivoted to the front end of saidfinger and comprising a working portion and spaced parallel outwardlyextending wings overlying said finger on each side thereof, said wingsbeing formed with rearward and outward projections having their undersides eoneavely curved and formed to In testimony whereof, I aflix mysignature, engage said broundfed pogtions as stopss, s ng in presence oftwo witnessesn rojections eing orme to project eyon said finger at oneextreme of their pivotal FRANK CASPER movement and to overlie saidfinger Within Witnesses: the confines thereof at the other extreme ofJOHN WHITE, their pivotal movement.
